The regular price of a pair of
jeans is $45. If there is a 30%
discount, how much do the
jeans cost after the discount?

Answer:

4w + 6

Step-by-step explanation:

Let width = w

Length = w + 3

Perimeter = 2*length + 2* width

                = 2(w +3) + 2w           {Use distributive property}

                = 2w + 2*3 + 2w

                =  2w + 6 + 2w              {Combine like terms}

                = 4w + 6

Step-by-step explanation:

Set up equation

[tex]\frac{5x}{3} +\frac{3x-2}{6} =2-3x[/tex]

Make 5x/3 and 2-3x have a denominator of 6. To do this, we multiply everything in 5x/3 by 2 and multiply everything in 2-3x by 6.

[tex]\frac{10x}{6} +\frac{3x-2}{6} =\frac{12-18x}{6}[/tex]

Add the Left fractions numerators and set them equal to the Left side.

13x-2=12-18x

13x=14-18x

31x=14

x=14/31

Answer:

f(2) = -1

Step-by-step explanation:

Looking at the graph, there appears to be two points at x = 2.  However, looking more closely, we see that the point (2, 4) is empty; this means the graph goes up to this point but does not hit this point.

The point (2, -1) is filled in; this means the graph hits this point.

Step-by-step explanation:

The value of f(2) on the graph of the piecewise function is -1

From the graph of the piecewise function, we have the following highlights

When x = 2, the function has corresponding values at y = 4 and y = -1

However, the graph has an open circle at y = 4 and a closed circle at y = -1

Closed circles show inclusiveness

This means that the actual value of f(2) on the graph is -1

Hence, the value of f(2) on the graph of the piecewise function is -1

To find the slope of a line, we can use the following formula:

[tex] \displaystyle \large{m = \frac{y_2 - y_1}{x_2 - x_1} }[/tex]

m-term stands for slope or gradient. The formula is useful whenever you want to find a slope of two points.

Let these be the following:

[tex] \displaystyle \large{(x_1,y_1) = (0, - 11)} \\ \displaystyle \large{(x_2,y_2) = (8, - 8)}[/tex]

Substitute the points in formula:

[tex] \displaystyle \large{m = \frac{ - 8 -( - 11)}{ 8 - 0} }[/tex]

Negative multiply negative always come out as positive.

[tex] \displaystyle \large{m = \frac{ - 8 + 11}{ 8 - 0} } \\ \displaystyle \large{m = \frac{ 3}{ 8 } } \\ [/tex]

Since m stands for slope, we can say that:

[tex] \displaystyle \large \boxed{ \tt{slope = \frac{3}{8} }}[/tex]

Answer:

Step-by-step explanation:

(x₁  ,y₁) = (0,-11)     & (x₂ , y₂) =   (8,-8)

Slope = [tex]\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]

          [tex]=\dfrac{-8-[-11]}{8-0}\\\\=\dfrac{-8+11}{8}\\\\=\dfrac{3}{8}[/tex]

Step-by-step explanation:

                       a+b > c

                       a+c > b

                        b+c > a

A)triangle is possible with these measurements

B)triangle is not possible with these measurements

            2+3 >6

             2+6> 3

             3+6>2

C)triangle is possible with these measurements

    90+45+45=180 degrees(sum of interior angles of a triangle is 180 degrees)

               180=180

D)triangle is not possible with these measurements

    90+60+60=180(sum of interior angles of a triangle is 180 degrees)

      90+120   =210 degrees

  sum of interior angles of the triangle is more than 180 degrees

Therefore it is not a triangle

Answer:

c

Step-by-step explanation:

Given direct variation between y and t , then the equation relating them is

y = kt ← k is the constant of variation

To find k use the condition y = 27 when t = 4 , then

27 = 4k ( divide both sides by 4 )

6.75 = k

y = 6.75t ← equation of variation

When t = 12 , then

y = 6.75 × 12 = 81

Hi

Your question would be better with  "  Could you help me please ? " at the end. Quite sure your mum told you that some time in the past.

I will show you how to solve but you will do the calculus. Math is all about rules, methods and training.  If you dont practice, you will never progress.

rule  :  you must know by heart your remarkable identities.

Here we have  :   ( 4x-3)² - (2x+5)² = 0

It 's of the  form  A² -B² =  ( A+B) ( A-B)  

here A is  :   4x-3   and  B is  2x+5  

Now let's apply rule  :   ( 4x-3)² - (2x+5)² =  ( (4x-3) +( 2x+5) )  ( (4x-3) - (2x+5)

                                                                  =    ( 4x-3 +2x+5 )  ( 4x-3 -2x-5 )

                                                                  =     ( 6x +2)  ( 2x-8)  

so :  ( 4x-3)² - (2x+5)² =  ( 6x +2)  ( 2x-8)  

so  ( 4x-3)² - (2x+5)²  = 0   means  :  ( 6x +2)  ( 2x-8)    = 0

Rule A*B = 0 if A = 0  or B = 0

A  is  6x+2     and B = 2x-8

So I let you now work  :  

You have to solve :   6x+2 = 0

and   2x-8 = 0

Solutions of this two calculus will be the solutions of  ( 4x-3)² - (2x+5)²  = 0  

Have fun !                                    

=========================================================

Explanation:

If we tried the x coordinate of choice A, then,

y = -3x-7

y = -3*2-7

y = -6-7

y = -13

This shows that the point (2,-13) is on the line and not (2,-1). This rules out choice A, and also choice E.

Let's try x = -2

y = -3x-7

y = -3*(-2)-7

y = 6-7

y = -1

This shows that (-2,-1) is a point on the line, and it points us to choice C being the final answer. This rules out choice B.

If we tried x = 1, then,

y = -3x-7

y = -3*1-7

y = -3-7

y = -10

Which shows that (1,-10) is a point on this line, which rules out choice D.

The visual summary is shown below as a graph. Only point C is on the red line.

x - 6 = -18

x = -18 + 6

=> The correct answer will be Option B - x = - 12

Answer:

total surface area of cube is 6 * area of one side

therefore area of one side is given 64cm^2

thickness is also given 5cm .

TSA is 64*5 = 320cm^2

hope it is helpful

Answer:

288 cm²

Step-by-step explanation:

The square base has an area of 64 cm².

That means the sides of the square base measure 8 cm.

The perimeter of the base is P = 4 * 8 cm = 32 cm.

The lateral area is Ph = 32 cm * 5 cm = 160 cm².

The two bases are congruent, and their combined area is 2 * 64 cm² = 128 cm².

The total surface area equals the sum of the lateral area and the area of the bases.

SA = 160 cm² + 128 cm²

SA = 288 cm²
